This invention'relates to a water closet of i the bottom thereof with an outlet for the jet passage through whicha stream of water was delivered upwardlyand directed toward the ascending passage of the siphon for the purpose of assisting in the removal of the solids from the bottom of the bowl and creatinga quick siphonic action "through the main siphon, thereby emptying the bowl of its contents. Ithas been found'in practice that a jet passage having its outlet thus located isobjcctionable because it forms a pocket in which the acids of urine and the lime in the water collect and corrode and eventuuseless, thereby causing the closet to flush out sluggishly when same is flushed. There is no way of emptying ,the liquids in this pocket except by soaking it out with a small cloth. and sharp instrument, projected into it, or by means of a separate passage cast in the bowl leading from the interior of the bowl to the outside of the same and provided with a screw cap to be removed when the said pocket is to be emptied of its contents. This is hardly ever done by the workmen when they are-sent to remove the water from the bowl to prevent freezing in unoccupied buildings. The result is that the liquids in said pockets freeze and burst the bowl at this locat-ion thus necessitating the installation of a new bowl.

It is the purpose of this invention-to provide a water closet of this character with a jet passage which eliminates this objection the outlet of which passage is so located that the same forms no pocket in which acids of urine and the limein the water can collect, corrode and clog, and when the water in the closet is removedto prevent freezing in unoccupied buildings there is no water left in this jet to freeze due to the absences of a pocket in same, and this jet is so located that when the closet is flushed thewater from the jet strikesthe solids from the back and forces the same throughthe main siphon, thereby 5 creating a 7 quick 'siphonic discharge action on the contents in the bowl.

To that end this'i'nvention consists en erally in providing this closet bowl with a et passage which has its outlet arranged above the bottom of thebowl'and preferably opposite the siphon whereby the jet outlet is;

not only concealed but-also cannot become I sisting in the emp ying operation ofthebowl.

In the accompanying drawings clogged and operates most effectively in .aisj-H Figure 1, is a vertical longitudinal section of a water closet embodyinginy improve-i ments; 7

Although my invention is applicable to water closets which may be variously con-f structed so far as the details are] concerned, 7 I

that shown in'the drawings comprises a bowl 1'l1aving an internal flushing rim 2 and a water supply pipe3, or inlet connected with the rear part of this rim. i I

1 Underneath the bowl is arrangedthe one i let at for the closet which maybe connected with the drain or soil pipe in anyj'suitable manner. During thenormal operation of the. closet the contents of the bowl are removed therefrom througha siphon preferably arranged onthe front part of the closet and having an ascending passage 5 which extends upwardly from the bottom or lower part of the bowl and adescending passage "6, extenddownwardly from the upper end of the ascending passage 5 to the outlet 4. V

Upon admitting water into the bowl from the supply pipe and flushing rim so as to cause the water in the bowl and ascending passage 5 to rise until it escapesinto the"descending passage 6a siphonic action is pro-j duced in a well known manner which causes the contents of the bowl to be drawn from the bowl upwardlythrough the asc'ending' passage 5 and discharged downwardly through the descending passage-Hand out of the outlet to the waste pipe. After (each flushing operation the wateriremaining in the bowl seals the lower end ofthe ascending passage 5 so as to prevent the escape' ofan sewer gas from the drain pipe" through the siphon into the building, the level ofithe Water at this time not rising above the upper ends of the ascending and descending passages of the siphon;

It sometimes happens that the main siphon becomes clogged by reason of children dropping tooth or hair brushes, drinking glasses or other hardsubstances in the bowl so that they are drawn into the passages of the siphon and choke the same. WVhen this occurs in closets as heretofore constructed the subsecuent addition of water upon opening the ushing valve will eventually fill the bowl completely with water and often flow from a the top of the latter to the floor causing damage and inconvenience. To avoid this an overflow is provided which is preferably arranged on the rear side or part of the closet and which consists of an ascending passage 7 extending upwardly from the bottom of the bowl anda descending passage 8. extending downwardly from the upper end of the ascending passage 7 to the outlet 4:. The upper ends of the ascending and descending passages of the overflow are arranged higher than the upper ends of the ascending and descending passages of the main siphon so that no Water will flow over the turn or highest part of the overflow while the water is free to flow over the turn or highest part of the siphon. But if the siphon is obstructed either completely or to such an extent that the water is not carried away from the bowl. by the siphon as fast as it is supplied by the 'fi pipe then the water will rise in the bowi and in the ascending passage of the overflow until it reaches the. highest part of the same after. which discharged into the be .i by the flush pipe will flow downwardly through the descending passage of the overflow and escape through the outlet 4 to the drain or sewer. Inasmuch as the ascending passage of the overflow is filled with water fromthe bowl this overflow is water sealed andsewer gas is prevented through the same from the V i pipe into the building. 7 Itwill thus be noted that so long as the siphon is inan operative condition to carry away the contents of the bowl when the flushing water is supplied thereto, the overflow is inactive; when the siphon fails to carry away the contents of the bowl then the water rises to an abnormal height in the bowl, whereby'the overflow becomes active and carries away the water from the bowl to the outlet, thereby preventing flooding of the room in which the closet is installed. When this abnormal rising of the water in the bowl is observed this serves as a signalthat some thing is wrong with the siphon so that a p llilimber can be calledto correct the defect. e closet is not intended to be used when only theloverfiow is available since the pri mary function of the latter is that of a safety device to prevent overflowing of the'close't 1 additional water and also as an indicator to call attention to a clogged condition of the siphon.

The descending passage of the overflow is of larger cross section throughout its length than the companion ascending passage sothat this descending passage has a larger capacity than the ascending passage co-operating therewith. By this means a siphonicaction The lower ends of the ascending passagcs' of the siphon and overflow are on the same level so that theyare both sealed simultaneously when water is supplied to the bowl and thereby effectually prevent the entrance of sewer gas from entering the building either through the siphon or through the overflow and also breaking the siplionic action simultaneously and avoiding a gurgling noise.

Along the inner side of the overflow the bowl is provided with a jet passage 9 which is preferably upright and communicates at its upper end 10 with the inlet 3 so as to receive a water supply therefrom while the outlet 11 at its lower end faces downwardly and is in line with the lower end of the ascending passage of the overflow. g

The outlet of the jet passage is therefore concealed when viewing the bowl from above and it is also arranged above the bottom of the bowl so that any solids deposited in the bowl will not fall on the ct outlet and accumulate over the same. Nor does the same form a pocket in which acids in the urine and lime in the water can be collected, thereby preventing this jet outlet from being corroded and eventually clogged, as would'otherwi'se be the case and impair the function 'of the closet.

' Instead of this the st outlet isal'ways clear of obstructions and when water is admitted through the inlet 3 for flushing the closet, part of this water passes from the rim '2 downwardly along the inner side of the bowl and at the same time a jet of water is directed downwardly and inwardly from the outlet at the lower end of the jet passage which jet strikes the mass of solids resting on the bot tom of the bowl on the back and pushes the same laterally toward the lower end of the ascending passage of the siphon and causes the latter to be filled quickly with water and the solids to be carried quickly through the siphon and the outlet onthe lower side of the closet.

It will be apparent from the foregoing that in this organization the three passages 57; 8 and 9 are located in the same part of the bowl thereby simplifying the construction and re- It will be noted that in this construction the auxiliary overflow siphon 1S *Wholly unob; structed and has no communication at its top with the Water inlet at the top of the bowl, and that the jet passage also is wholly unobstructed andhas no'coinn'iunieation any kind at its top with the top of the overflow passe or +he top of the main siphen. f

Moreover when Water is present in the bottom of the bowl this Wateraots as a trap or seal for the lower ends of the ascending passages of the main siphon and the auxiliary I overflow and also for he lower end of the jete passage. 7

Due to this constructio he Jassageo gas from the sewer or d: into the building is positivel .is assisted by the ESTQSSUIG of the jet, tnereb y safeguarding; the bowl againstoverflow in the eventthat the main siphonshould become of the dam of theoverflow occurs this serves clogged when rising ofthe Water to the level asatelltale'or arning that cleaning out of V the bowl isneoessary.
